At present, the Main Means of transformer station's thermometric is to carry out infrared measurement of temperature with infrared thermometer.But when infrared thermometer carries out thermometric to equipment in switch cubicle, ability is greatly limited, and first the glass window of switch cubicle affects infrared measurement of temperature effect, even if use the special-purpose infrared measurement of temperature glass window effect neither be very desirable; The second, in switch cubicle, closely, some equipment are difficult for observing because blocking mutually structure, have more increased the difficulty of thermometric.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, easy to operate switch cabinet of converting station temperature measuring equipment, not only can make staff more fully the temperature in switch cubicle be measured, and the data of measuring are more accurate, thereby avoid device fails, guarantee that electric system can better work.
The technical solution of the utility model:
A kind of switch cabinet of converting station temperature measuring equipment, it is characterized in that: described switch cabinet of converting station temperature measuring equipment comprises temperature detecting module, signal transmitting and receiving module and platinum resistance thermometer sensor,, described platinum resistance thermometer sensor, is connected with signal transmitting and receiving module one end by temperature detecting module, and the signal transmitting and receiving module other end is connected with MICROCOMPUTER PROCESSING controller.
Described temperature detecting module is the temperature measurement circuit forming with integrated temperature sensor.
Described signal transmitting and receiving module is the integrated transceiving chip of monolithic radio frequency.
The integrated transceiving chip of described monolithic radio frequency is NRF401.
The beneficial effects of the utility model:
The utility model provides a kind of simple in structure, easy to operate, equipment that can make staff more fully the temperature in switch cubicle be measured, the in the situation that of high-speed mobile or vibration, antijamming capability is strong, highly sensitive, error is little, has very high promotional value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the circuit theory diagrams of the utility model signal transmitting and receiving module.
Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described
.
As shown in Figure 1, a kind of switch cabinet of converting station temperature measuring equipment, comprise temperature detecting module 1, signal transmitting and receiving module 2, in described switch cabinet of converting station temperature measuring equipment, be provided with platinum resistance thermometer sensor, 3(PT100), platinum resistance thermometer sensor, 3 is connected with signal transmitting and receiving module 2 one end by temperature detecting module 1, and signal transmitting and receiving module 2 other ends are connected with MICROCOMPUTER PROCESSING controller 4, temperature detecting module 1 contains integrated temperature sensor 5, and signal transmitting and receiving module 2 is provided with the integrated transceiving chip of monolithic (NRF401) 6.
As shown in Figure 2, XC1: crystal oscillator input; XC2: crystal oscillator output; Here adopt 4MHZ benchmark crystal oscillator.VDD: chip power ,+2.7-+3.6V, generally gets 3V.VSS: power ground end.FILT1: loop filter.VCO1, VCO2: input inductance.DIN: data input.DOUT: data output.RF_PWR: transmission power adjustment input end.FREQ: channel selection end, during FREQ=0, frequency is 433.92MHZ; FREQ=1 frequency range is 315.16MHZ.ANT1, ANT2: dual-mode antenna terminal.PWR_UP: economize on electricity control input end, value is 1 o'clock, slice, thin piece is in running order; Value is 0 o'clock, and slice, thin piece is in holding state.TXEN: transmitting-receiving control end, value is 1 o'clock, slice, thin piece is in emission state; Value is 0 o'clock, and slice, thin piece is in accepting state.The access of antenna: ANT1, ANT2 are the inputs of LNA while receiving, and the output of power amplifier while sending, and the antenna that connects NRF403 is connected to NRF403 with differential mode.The loaded impedance of recommending in antenna end is 400 ohm, this figure is a typical schematic diagram that adopts differential mode, radio-frequency power amplifier output is two open circuit triodes, be configured to difference matching method, the VDD of power amplifier must pass through collector load, when adopting difference tours antenna, VDD must input by the center of tours antenna.
Specific works process:
First platinum resistance thermometer sensor, 3 is fixed in transformation switch cabinet, by the temperature detecting module 1 that contains integrated temperature sensor 5, detect and the result of detection is sent to MICROCOMPUTER PROCESSING controller 4 by being provided with integrated transceiving chip (NRF401) 6, operating personnel are by the Data Detection result of observation MICROCOMPUTER PROCESSING controller 4, can judge, if the temperature in discovery switch cabinet of converting station surpasses setting value, control software bright light is reported to the police, and it is processed in time, avoid breaking down.
